研究了Gorenstein内射模,介绍了一类Gorenstein内射维数有限的模,即研究的(n,m)-强Gorenstein内射模,并讨论了这类模的上合冲及性质.
Gorenstein injective modules were studied.Furthermore,a class of modules with finite gorenstein dimensions were introduced,namely,(n,m)-strongly gorenstein injective modules.And the properties of its cosyzygy were also obtained.
